thank you gentlemen. great advice.
my doubt is regarding this: " Only jump start your Crossfire with a booster battery"
does it mean that the current delivered by the booster is not as high as the 1 from another car, so this way there is no overload that may damage something? (or not so much chance to do so?)
it is the only way i understand why using the booster is ok but not the other cars.
what do you think?
